| Research Abstract |
Single-crystalline, nano-crystalline and amorphous SiC nanotubes were successfully synthesized by ions irradiation of polycrystalline SiC nanotubes. The critical irradiation damage of completely amorphization of polycrystalline SiC nanotubes decreased with increasing the atomic weight of irradiation ion. A polycrystalline/amorphous hetero-structure SiC nanotube, in which polycrystalline SiC and amorphous SiC coexisted in the same nanotube, was also synthesized by ions irradiation with masks in front of polycrystalline SiC nanotube.
